Epidemiology of ischaemic heart disease in France

Cardiovascular disease is the leading cause of death worldwide. Ischaemic heart disease (IHD), including acute coronary syndromes (ACS) with or without ST-segment elevation and chronic coronary syndromes, is one of the main causes.

To describe the epidemiology of IHD in France in 2022.

Adults hospitalized due to IHD in 2022 were identified in the French National Health Data System. The characteristics, hospital management and one-year outcomes of patients were described. The IHD prevalence among people alive on 01.01.23 was estimated by combining previous hospitalizations and people in receipt of 100% coverage for a registered long-term disease. IHD-related mortality was estimated from death certificates.

In 2022, 242,227 adults were hospitalized for IHD in France (452/100,000 person-years); 2.98 million prevalent cases of IHD (5.6% of the adult population) and 31,391 IHD-related deaths (4.8% of all deaths) were recorded. The average age at hospitalization for IHD was 69.3years and 29.0% of patients were women. Exposure to cardiovascular risk factors was high. The average length of hospitalization was 4.9 days, 55.9% had undergone a percutaneous coronary intervention and 4.5% a coronary artery bypass graft. The in-hospital death rate was 3.6%. Six months after the index hospitalization, 22.0% of patients had been admitted to a rehabilitation service (42.9% for STE-ACS). In the year following the index hospitalization, 84.5% of patients had received antiplatelet drugs, 82.6% a statin, 68.8% a beta-blocker and 67.7% a renin-angiotensin-aldosterone system treatment. One year after index hospitalization, the rate of rehospitalization for IHD was 29.9% and the rate of all-cause death was 9.3%.

The burden of IHD remains high in France. These results suggest that primary prevention of IHD should be maintained and improved, as well as secondary prevention, to improve the prognosis and quality of life of the 3 million patients with coronary disease.
